I have this problem too. It stops whenever there is access problem and it doesnt retry automaticly because it gives you information if I would like to see the error...This doesn't make sense and I should be able to disable it...
What kind of errors/warnings do you mean?
If an error occurs at copying a file to a remote server,
it would be nice to have a checkbox on every errormessage or warningmessage like "Do not show this Errror/Warning again"
